GAS-STOVE.

SPECIFICATION forming part of Letters Patent No. 649,298, dated May 8,1900.

Application filed December 15, 1898. flerial No. 699,307. (No model.) i

To aZZ whom it may concern:

Be it known that I, HENRY A. GUIGNON, a citizen of the United States,residing at Corry, in the county of Erie and State of Pennsylvania, haveinvented certain new and useful Improvements in Gas-Stoves; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to gas-stoves; and it consists in certainimprovements in the construction thereof, as will be hereinafter fullydescribed, and pointed out in the claims.

More particularly, the invention relates to stoves having an open front,with a fireback and a fine or fines for deflecting the heated gases froma direct entrance to the exit pipe or fine in such a manner as tocommunicate the greatest possible portion of the heat in said gases tothe surrounding air without so obstructing the passage of said gases asto cause their escape to the air.

The invention is illustrated in the aocompanying drawings, as follows:

Figure 1 shows a section on the lines 1 l in Figs. 2, 3, and 4. Fig. 2shows a front elevation of the stove. Fig. 3 shows a section on the line3 3 in Figs. 1 and 2. Fig. tshows a section on the lines 4 4 in Figs. 1and 2. Fig. 5 is a vertical section on a line extending through theopening 0 in Figs. 1 and 4.

The stove comprises the following general parts: a base A, side lines13, top C, fireback D, and a burner E.

The stove is preferably formed by connecting the top with the basethrough the medium of flues h, leaving an opening from front to rearthrough the stove, in which the fireback D and burner E are inserted.The burner E is arranged in proper relation to throw its flame on thefireback D, which is preferably provided with material adapted to becomeincandescent by the action of the flame upon it. The base as constructedcomprises an upper portion a, struck up from sheet metal with the sidesextending downwardly, said sides having a flange a, which extends aroundthe outer periphery of the base. A plate a with flanges a which arearranged within the side of the part A, forms a false bottom. Partitionsa are secured to this false bottom and to the top part a and extendinwardly from the side edges to the points near the center of said base,leaving a space between their inner ends, as shown in dotted lines inFig. 3. A bottom plate a is placed under the false bottom and has itsedges a crimped over the flange a, thus securing the whole structuretogether. Legs A maybe secured to this base and also a fender F, ifdesired. Flue-pieces B are preferabl y arranged at each side of theburner and open into the base through the openings a a A partition I)divides these flue-pieces into two fines b and b whichopen through theopenings a d to the front and rear portions of the base, respectively.The top 0 is preferably formed of sheet metal struck up with its sidesextending upwardly, said sides having a flange 0', extending around theupper edges. An opening 0 is arranged in said top, preferably just infront of the top of the fireback D.- An in'flector 0 extendsdownwardlyand in front of said opening. A false top 0 is provided withflanges which fit in said sides of the parts 0. Partition-plates c areriveted or secured to this false plate and embrace an upturned portion 0from the bottom of the parts 0, thus forming the partition entirelyacross the center of the top. A top piece 0 is crimped at 0 over theflanges 0', thus uniting and closing the top. Openings 0 and 0 throughthe bottom of the parts copen into the dues Z) and 6 respectively, thepartitions formed by the plates 0 and c registering with the partitionsb and forming front and rear chambers c and 0 An exit flue or pipe Gisarranged in the top of the rear chamber of the top portion 0. The pipehas a flange g at its lower edge, which rests upon the plate 0 .A pieceg is secured within the pipe and extends into the interior top, where itis flanged outwardly to secure the pipe in place.

In operation the heated gases pass up into the front portion of the top,down the fines b, around the partitions a, up the flues 11 through therear portion of the top to the exit-flue G. This does not so retard thegases as to expel some of them into the room or chamber in which thestove is used, but at the same time does so hold the gases as to allowthe heat to dissipate largely into the surrounding air without chokingthe exit-flue G. It is common practice with stoves of this character toallow the heat of the gases to pass directly into the exit-flue G, butto provide the exit-flue G with a damper, which reduces the passage toso small a size as to expel more or less of the products of comblistion.In the use of natural gas this is particularly. bad, because theproducts of combustion contain a great deal of moisture, which iscondensed upon any cool surface, especially windows. With a stove of thecharacter herein described all the qualities of the open front are givento the stove without this effect. The arrangement of the fines b at theside and in advance of the burner so 10- cates it as to be away from awall or woodwork which may be immediately at the rear of the stove, andwhile the gases have their greatest heat they are in this manner heldthe farthest remote from the part of the stove which is usually placedin proximity to the wall. By making the flues at the side and leavingthe center open the fireback and burner may be readily put in place andremoved and repaired without disturbing other portions of the stove.

The burner is formed, preferably, by bending sheet metal substantiallyinto the form shown, with perforations e along the top. A perforatedplate E is placed diagonally across the burner between the jet-orificese and the feed-pipe c. This so diffuses the gases as to effect an evenflame throughout the length of the burner. Amixer E is arranged on thefeed-pipe, as commonly.

WVhat I claim as new is- 1. In a gas-stove the combination of a firebackarranged to be directly exposed at the front; a burner arranged to throwits flame upon said fireback; a flue at the side of said firebackforming a part of the combustionchamber being connected at its top withan opening leading from the firebaclr, and at the bottom with thestove-exit.

2. In a gas-stove, the combination of afireback arranged to be directlyexposed at the front; a burner arranged to throw its flame upon saidflreback; a flue at the side of said fireback forming a part of thecombustionchamber, said flue being connected at its top with an openingleading from said fireback; and a second flue leading from the bottom ofthe first flue and being also placed at the side of the stove, said fluebeing connected at its top with the exit.

3. In a gas-stove, the combination of a fire-.

back arranged to be directly exposed at the front; a flue at the side ofthe fireback form ing a part of the combustion-chamber, said flue beingconnected at its top with an opening leading from said fireback; abottom flue leading from said first flue along the bottom of the stovetoward the center of the stove and back to the same side of the stove asthe first flue; and a second flue arranged at the side of the stovebeing connected at the bottom with said bottom flue and at the top withthe exit.

4. A gas-stove having an air-flue at its side forming a part of thecombustion-chamber; a burner in the rear of said combustion-chamber; afireback in said stove, the stove being open from front to rear wherebyaccess can be had to the burner and fireback from the rear.

5. A gas-stove having air-fines at its sides forming apart of thecombustion-chamber; a burner in the rear of said combustion-chainber; aremovable fireback in said stove, the stove being open from front torear whereby the fireback may be removed and access may be had to theburner from the rear.

6. In a gas-stove, the combination of the base having the partition, a afireback arranged to be directly exposed at the front; a burner arrangedto throw its flame upon said flreback; the side fiues, U11 theinnerwalls of one of said flues forming the side wall for the fireback thetop having a partition dividing it into a front and rear portion, thefront portion being in connection with the flue, Z), and the rearportion with the flue, b and an exit-pipe from the rear compartment ofthe top.

7. In agas-stove base, the combination of the top part, at, having theflange, a; afalse bottom, a the bottom, of, crimped on the flange, a;and the partition, a. x

8. In a gas-stove top, the combination of the bottom piece, 0, havingthe flanges, c; the false top, 0 having the flanges, 0 the plates, 0 0forming the central partition at the top; and the top, 0 having thecrimped edge,

In testimony whereof I affix my signature in presence of two witnesses.
